well i want you to know that i do have a little experiance with this. but signs that the child may give you are: scared when you yell(like more than normal) and if you have a person in mind that it might be, ask the child questions about this person and signs of embarrasment or awekwardness may arise, the child may try to defend the person as soon as you ask about him, (this could be because he has threatened the child) if you would like to continue, email me, if you can tell me how your child is acting out i may be able to help further jesus_freak2122123@yahoo.com hope this is some help
